13 R I/O
GPIO port, can be used as LED drive PWM output, default
corresponding to red light
14 CW I/O
GPIO port, can be used as LED driver PWM output, default
corresponding to cold white light
15 RX I/O
Serial port receiving pin UART RX
16 TX I/O Serial port sending pin UART TX
Note: P stands for power supply pin, I/O stands for input and output pin, AI
stands for analog input. If you have your own requirements for the light color
controlled by the PWM output, please contact us.
